Fertility specialists have long noticed a relationship between thyroid disorders and reproductive health issues including irregular periods, difficulty getting pregnant, and multiple miscarriages early in pregnancy. During Thyroid Awareness Month and with new research, it’s worth knowing about a not uncommon and treatable problem that may be affecting your plans for a new family.

An underactive thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism) may be present even in healthy young women and can affect reproduction at every stage from conception, poor fetal growth, premature birth and stillbirth. Not having enough thyroid hormone, for example, may affect ovulation and embryo development. It may also signal an underlying autoimmune disorder that affects fertility.
